I am convinced that because the first flight is operated by CX, my itinerary is ineligible for online check-in. If I am only flying on JL operated codeshare, I might be able to do it.
The first flight of the itinerary for which a customer is checking in must be operated by American Airlines, American Eagle, AmericanConnection, British Airways, Iberia or Japan Airlines.
